1. What Ceretec Stabilized is and what it is used for

This medicine is a radiopharmaceutical for diagnostic use only.

It contains an active ingredient called "exametazime", which is mixed with a radioactive component called "technetium" before use. Once injected, it can be detected from outside the body by a special camera used in the examination.

Ceretec Stabilized is administered before an examination and, along with a special camera, helps to see inside a part of the body.

The examination with Ceretec Stabilized is used to:

  • Help your doctor determine how much blood is reaching your brain. This may be important to know after a stroke, a head injury, if you have seizures or epilepsy, or to distinguish between Alzheimer's disease and other similar types of dementia. It may also be used to aid in the diagnosis of brain death.

The administration of Ceretec Stabilized involves receiving a small amount of radioactivity. Your doctor and nuclear medicine doctor have considered that the clinical benefit you will obtain from the procedure with the radiopharmaceutical outweighs the risk of radiation.

Doctor consultation

In case of doubt, it is important that you consult your nuclear medicine doctor who is supervising the procedure.

If you are pregnant

The nuclear medicine doctor will only administer this medicine during pregnancy if the benefit is expected to outweigh the risk.

If you are breastfeeding

Do not breastfeed if you receive Ceretec Stabilized. This is because small amounts of "radioactivity" may pass into breast milk. If you are breastfeeding, the nuclear medicine doctor may wait until you finish breastfeeding before using Ceretec Stabilized. If it cannot be delayed, the doctor may ask you to:

  • interrupt breastfeeding for 12 hours or more.
  • use artificial milk to feed your child, and
  • express breast milk and discard it.

Please consult your nuclear medicine doctor when you can resume breastfeeding.

Driving and using machines

Ceretec Stabilized is unlikely to affect your ability to drive or use machines.

Consult your doctor if you can drive or use machines after receiving Ceretec Stabilized.

Ceretec Stabilized contains sodiumand, depending on when it is administered, the sodium content may be higher than 23 mg (1 mmol), which should be taken into account in the treatment of patients with low-sodium diets.
